If you are already using one of our ProXR series controllers connected to the Serial Port or USB Port, then you will not have to make any software changes. This device works as though it were directly connected to a serial port on your PC, offering 100% transparent wireless serial communications.
With all the control and backward/forward compatibility you have come to expect from the ProXR series command set, this controller allows you to send simple commands to activate relays, read the status of relays, activate up to 16 relay timers, and control up to 256 total relays using the XR expansion port. All relays are electronically latched, simply send a command to turn the relay on, send a different command to turn the relay off.
